To (til whom it 711/151 concern:

Be it known that I, LEROY LINDSEY, a citizen of the United States,residing at Seymonr, in the county of Wayne and State of Iowa, haveinvented certain new and useful Improvements in Attachments for Corn-Planters, of which. the following is a specificatlon.

The object of this invention is to construct a marking attachment forcorn-planters comprising two bars each having a pivotal connection withthe main frame and adapted to be moved to rest in the lengthwisedirection of the main frame when not in use for transportation.

In the accompanying drawings, Figure 1 is a plan view of a corn-planterembodying my improvements. Fig. 2 is a side elevation. Fig. 3 is anisometrical representation of the rear portion of the main frame as seenfrom its under face. Fig. 4 is an isometrical representation of theouter end of one of the marker-bars, and Fig. 5 is an isometricalrepresentation of the pivotal connection of one gf the marker-bars withthe stationary cross- The corn-planter shown in the drawings is of anold construction and comprises the main frame 1, supported by the axle 2and wheels 3. The runner-frame 4 supports the seedboxes 5 and runners orfurrow-openers 6. The forward portion of the main frame has a pivotalconnection with the runner-frame. A tongue 7 has a connection with therunnerframe.

The mechanism for operating the seeddropping devices is not shown in thedrawings, as it forms no part of my invention.

To the rear bar of the main frame is connected a cross-bar 8 by the bolt9. To the under face of the cross-bar are secured plates 10, which restagainst the under face of the rear bar of the main frame, which inconjunction with the bolt 9 serves to form a substantially fixedconnection between the cross-bar and main frame. Eachgend of the crossbar supports an angle-bolt comprising the branches 1 1 and 12, locatedat an acute angle with respect to each other. The angle-bolt at one endof the cross-bar has a connection with the bar 13 by the branch 12 ofthe bolt passing through it. Nuts are placed on both ends of the bolt.

To the free end of the bar 13 is connected a marker-arm having a portion14 secured to the under face of the bar by the bolts 16 and a portion 15turned at an angle diagonally across the bar. This markerarm isadjustable bodily in the lengthwise direction of the bar 13 by reason ofthe series of holes 26, receiving the bolts 16. In the free end of thebar 13 is located a cotter 17. To the other endof the cross-bar 8 isconnected a bar 18 in the same manner as the bar 13 is connected. Thisbar 18 supports a marker-arm, also a cotter 19. This marker-arm isadjustable in the lengthwise direction of the bar 18 by reason of theseries of holes 20, receiving the bolts 21.

A sheave 22 is connected to the under face of the tongue 7. A rope 23has one end con.- nected. to the cotter l7, and its other end isconnected to the cotter 19. This rope passes over the sheave 22 and hastwo knots 24 and 25, one located each side of the sheave.

With the parts in the position shown at Fig. 1 the arm 18 is turned soas to occupy a position lengthwise of the main frame of the planter, andthe arm 13 is in an operative position. The knot 24 in the rope restingagainst the sheave holds the arm 13 in proper working position. Inmoving the planter over the ground the portion 15 of the markerarm 13will form a depression in the ground, serving as a guid e in planting.By the employment of the cotters should the bars or markerarms strike anobstruction the cotters would pull out before the rope would break. Bythe employment of the angle-bolts for forming a connection between thecross-bar and the bars supporting the marker-arms it will be seen thatthe bars have a vertical swinging movement, the branches 11 of theanglebolts acting as centers, and in turning the bars into aninoperative position their free ends will rise so as to free the ground.

I claim as my invention- 1. A marker for corn-planters comprising a mainbar, and two marker-bars, one pivoted to each end of the main bar, theconnection consisting of an angle-bolt, one branch of the bolt connectedto the main bar, and

the other branch of the bolt connected to the when severe strain isapplied to the markermarker-bar. bar.

2. A marker for corn-planters comprising a marker bar, a cottersupported by the 5 marker-bar, and a rope having one end con- Witnesses:
